I have an Alma Linux 9 server on AWS EC2.
using 3rd generation Intel Xeon Scalable processor - Ice Lake 8375C and 64GB Ram.
At bootup, I get this error message.
dmesg | egrep -i ‘error|critical|warn’
[ 1.492188] unchecked MSR access error: WRMSR to 0x199 (tried to write 0x0000000000000800) at rIP: 0xffffffff8653a4f1 (__wrmsr_on_cpu+0x31/0x40)
When I switch to this instance type, it does not give that error:
Intel Xeon Scalable processor (Skylake 8175M or Cascade Lake 8259CL) with new Intel Advanced Vector Extension (AVX-512) instruction set
I would prefer to use the 3rd gen cpu, but I don’t know if that error message is a problem.
Btw, I also saw the same error message on AL8
